Each candidate for Montana office has the opportunity to agree the following campaign ethical principles. In spirit of full disclosure I am listing the Montana Office of Political Practices Code of Fair Campaign Practices that I have agreed to, in addition to signing the Pro-Truth Pledge:

There are basic principles of decency, honesty, and fair play that every candidate for public office in the United States has a moral obligation to observe and uphold, in order that, after vigorously contested but fairly conducted campaigns, our citizens may exercise their constitutional right to a free and untrammeled choice and the will of the people may be fully and clearly expressed on the issues before the country.

Therefore:
I will conduct my campaign in the best American tradition, discussing the issues as I see them, presenting my record and policies with sincerity and frankness, and criticizing without fear or favor the record and policies of my opponent and his party which merit such criticism.

I will defend and uphold the right of every qualified American voter to full and equal protection in the electoral process.

I will conduct my campaign without the use of personal vilification, character defamation, whispering campaigns, libel, slander, or scurrilous attacks on my opposition or his personal or family life.

I will not use campaign material of any sort which misrepresents, distorts, or otherwise falsifies the facts, nor will I use malicious or unfounded accusations which aim at creating or exploiting doubts, without justification, as to the loyalty and patriotism of my opposition.

I will not make any appeal to prejudice based on race, sex, creed, or national origin.

I will not undertake or condone any dishonest or unethical practice which tends to corrupt or undermine our American system of free elections or which hampers or prevents the full and free expression of the will of the voters.

Insofar as is possible, I will immediately and publicly repudiate support deriving from any individual or group which resorts, on behalf of my candidacy or in opposition to that of my opponent, to the methods and tactics that I have pledged not to use or condone.
